摘要
实验研究架空线缆的电磁脉冲(EMP)响应。利用有界波EMP模拟器和辐射波EMP模拟器产生的电磁环境,分别开展了架空线缆的响应实验,有界波模拟器下进行了4.6m长、0.5m高的单、多根短线缆响应实验,辐射波模拟器下进行了40m长、3.3m高的长线缆响应实验。实验测试了线缆在端接不同负载时端点处的电流响应,并与基于Agrawal模型的计算结果进行了对比。结果显示,两种实验环境下的测量和计算结果吻合较好。这表明,有界波EMP模拟器和辐射波EMP模拟器均可以开展线缆的EMP响应实验研究,并且实验结果也验证了运用Agrawal模型预测分析线缆EMP响应的有效性。
The response of aerial wires illuminated by electromagnetic pulse（EMP） has been experimentally investigated in terms of a bounded-wave simulator and a radiated-wave simulator, respectively. A short test single wire and multiple wires of 4.6m long were placed directly 0.5m high on the bottom plate of the bounded-wave simulator. Another wire of 40m long located 3.3m above the soil and 30m away from the radiated-wave simulator. The current responses of the wires which terminated with different loads were measured at one end. The Agrawal model of TL theory was adopted to compute the induced current of the test wires. The measured and the calculated results agree well, which shows that the environments produced by these two simulators can all be used to experimental investigate the response of aerial wires, and the Agrawal model is an effective method to estimate the current response of wire excited by incident HEMP plane wave.
